The Keysight 8664A signal generator is suited for basic receiver testing up to 3.0 GHz.Pulse width and delay can be internally adjusted between 50 ns and 999 ns, eliminating the need for an external pulse generator. Standard FM rates of up to 2 MHz and deviations to 10 MHz are suitable for many applications such as high-speed digital communications.

With Option 004 (low-noise enhancement), the 8664A can be used for out-of-channel receiver testing or as a clock source where having the lowest phase jitter is important.
Radar testing can be done by adding Option 008 (pulse modulation).
